VACUUM-TUBE SOCKET.

Application filed September 5, 1918. Serial No. 252,721.

To all whom it may concern:

Be it known that I, JoHN O. GAReAN,.a

citizen of the United States, residing at usage to which these sets are often subject,

it is necessary to provide a holder for them, of such construction that the tube shall not readily fall out. I

The invention comprises a socket intto which the tube is inserted-and to which it is locked by a bayonet slot construction acting in combination with a resilient means at the base of the socket which operates on the base of the tube to hold it in place. The invention is illustrated in the drawing of which Fig. 1 is an elevation of the tube and socket with a portionof the base broken away, and showing the device attached to a portion of a portable tele raph set,- and Fig. 2 is a planview looking ownward upon the device with thetube removed from the'socket.

As-shown in the drawing, the socket is adapted to be attached to a suitable por-' tion, preferably the inside of the cover 1 of a portable telegraph set, and 1s mounted on a base 2 which is fastened in any suitable manner to the cover 1. This. basecomprises a somewhat U-shaped member, having at each end offset portions 3 which extend in a direction parallel to the surface of the cover" to which it is attached. Two ratherthick strips of rubber 4, or. other suitable resilient material, extend across the U-,

shaped depression in the base 2, from'one portion 3 to the other portion 3 ends of said portions 3. These r1 ber strips are, ateach end, fastened to the portions 3 of base 2 by means of suitable screws 5.

A vacuum tube socket 6 is supported from the rubber strips 4 by means of a plate 7 permanently conu ected to the socket and opp t l it forming a part of the bottom wall thereof, which plate is attached to the rubber strips by means of the screws 8. In the bottom wall of the socket 6 and the plate 7 are a plurality of aligned apertures 9 through which are adapted to extend the electrodes 10 of a vacuum tube inserted in the socket. A stud 11 is rigidly mounted in the center of plate 7 of the bottom wall of the socket and centrally with respect to said apertures 9 and extends downwardly from the bottom of the socket into the U-shaped portion of bracket 2, A disk 12 is positioned against the bottomof plate 7, and has an aperture therein surrounding stud 11. This disk is of such diameter as to substantially cover the apertures 9 in the bottom wall of the socket and is normally held against the bottom of plate 7 by means of aspring 13 which extends between disk 12 and a washer 18,

'held on to stud 11 by a pin 14 at the outer end of stud 11.

The device which is shown in the form of a vacuum tube of any suitable construction theelectrodes will extend through the apertures. A slot 16 is provided in the side of socket 6 which is adaptedto cooperate with a pin 17 on the plug form a bayonet lock.

In the operation of the device, a tube is i inserted in the socket 6, the pin 17 entering slot 16, and the electrodes 10 entering apertures 9. As the tube is thrust into the socket sufliciently far to permit it to be turned so that pin 17 will enter the side portion of slot 16, the electrodes contacting with disk 12 will depress the same against the-action of spring 13. The compression of spring 13 Wlll thereafter tend to maintain the bayonet lock effective so that the tube will have no tendency to fall out. A provision of the resilient portions 4, on which, the socket and tube are mounted, preventsany vibrations or jars contributed to the casing to which the bracket 2' is attached, from seriously afiecting-the lamp.

It is well within the spirit of my invention to provide such astructure as would accommodate a plurality of such tubes; for

instance, the plate 7 might be extended in of the tube or lamp to more than one socket; the ends of the plate in that case would similarly rest on resilient members attached to a bracket. The only change necessary to be made would be in the size of the parts used.

What is claimed is:

1. A holder for vacuum tubes comprising a base, a cup shaped socket attached to said base and having a bayonet slot in its side, the bottom of saidsocket having a plurality of apertures therein, a stud secured to-and beneath said bottom, a disk slidable on said studand of such diameter as to substantially cover said apertures, a washer held ontheendof said shaft, and a spring around said shaft in, compression between said washer and disk.

2. A holder for vacuum tubes comprising a base having a pin extending from its side and a plurality of electrodes extending from its bottom, a cup shaped socket for said base having a bayonet slot adapted to receive said pin, the bottom of said socket having a plurality of apertures adapted to receive said electrodes, a stud extending centrally beneath and away from said bottom, a disk slidable on said stud and adapted tobear against the bottom of the socket and substantially cover said apertures, and a spring on said stud and bearing against said disk to hold it normally in position to cover said apertures.

3. The combination with a base having a plurality of projecting electrodes, of a socket having apertures adapted to receive said electrodes, a locking connection between socket and base, and a member yieldably aperture in its bottom wall to receive an electrode of a vacuum tube, and spring pressed means mounted on said socketand adapted'to contact with said electrode for holding said vacuum tube in said socket;

6. A holder forvacuum tubes compris-" ing a base, a socket mounted thereon havin apertures adapted to receive a plurality o electrode terminals, a stud mounted on said socket, and spring means on said studadapted to contact with said electrodes.

In witness whereof, I hereunto subscribe my name this 29th day of August A. D.
